hi Zac,

The capability that you describe does exist in the underlying Stage
library, but is not exposed through the stageros wrapper.  A patch to
expose that functionality would be warmly welcomed.  It would be nice
to follow the ROS API used by gazebo (http://www.ros.org/wiki/gazebo)
for setting and getting model states.
